The FLOW CONSULTANT ™continuously monitors input throughout the computational process. Warnings are issued and default data displayed for entries outside the manufacturer's recommendations or published standards.

Constants are built in for virtually every model of Orifice Plate, Nozzle or Venturi are included. Solve for Liquid, Gas and Vapor fluid states.

Accepted US standard for the use of orifice meters used to meter natural gas and other fluids.

ASME-3M

Accepted standard used by many industries for the metering of many fluid and in particular steam and water flow measurement.

ASME-PT6

For Throat Tap nozzles

ANSI 2530

The American National Standards Institute's (ANSI) standard that duplicates AGA 3

ANSI 2530/AGA3/ Buckingham/Spink

The original AGA/ANSI/ASME standard for the metering of fluid with the flange tap orifice Flowmeter. Once widely used by all US industries in designing flow measurement equipment, this standard has been superseded by the above reference documents.

API Chapter 14

The ANSI standards for the metering of Natural gas.

ISO-5167 (2003)*

The International Standards Organization's (ISO) Standard, now in three parts, for the metering of all fluid using Orifices (all tapings), Nozzles, and Venturi Meters.

Miller (1983 to date)

NX-19

S-GERGEquation of State for Natural Gas is widely used in Europe for custody transfer measurements. S-GERG requires input of the heat content BTU (Joules), the relative density (Specific Gravity) and the mole fraction of carbon dioxide.

Only The FLOW CONSULTANT ™software solves for fluid properties modules using the exact solution and not the generalized state equation used in most software. These solutions can be in error by several percent or more.

The Fluid Properties modules contain equation constants for computing the properties for hundreds of fluids. Fluid Properties constants The FLOW CONSULTANT ™ are maintained in accordance with all the current reference texts and standards.

Existing Flow Consultant users may note some older materials are no longer listed. These can still be used by Entering the Thermal Expansion Coefficient. Removed materials were Yellow Brass, Beryllium Copper, Cupronickel and Pyrex Glass. If you are upgrading data from older versions of the Flow Consultant, these will default to entering the thermal expansion coefficient.

Enter the Thermal Expansion Coefficient for pipe material and primary element material if your materials are not in the pick list.

The ISA SP1, SP2, etc are ISA standards compatible or identical to the work on noise done by Hans Bauman, Masonelian for control valves.

This work is considered the basis for the most practical solution for noise on restrictive devices available in the literature. It is the source document for the solution used for the Flow Consultant noise calculation.

The Flow Consultant is backed by Microsoft Access TM. Our software provides a utility to create and maintain multiple databases for easy to use, directory based storage. Create a new data warehouse by simply picking a name and destination.

The estimated uncertainty based on the measured and unmeasured variables used in the flow rate computation are combined in accordance with the selected standards procedures to give the overall uncertainty (Accuracy).

The estimated uncertainty of the discharge coefficient and gas expansion factor is computed using the appropriate standards. The user inputs the uncertainties of the other measured or unmeasured variables.
